Rapid detection of hydraulic linear surface deformation of hydraulic turbine blades
This paper involves the technical field of steel casting deformation detection,especially a cast-ing surface deformation detection tool and casting surface deformation detection method.By designing a rapid detection tool,the measuring screw is adjusted to contact with the surface of the casting and marked,the profile condition of the surface is copied to the measuring screw of the long cardboard,the blade is processed according to the process requirements,and then the detection tool is placed on the surface of the casting according to the marked position,and the gap distance between the screw and the surface is measured,and the deformation of the casting can be obtained.It solves the problem that large turbine blades can not he quickly measured at any time and anywhere at the casting production site,and provides a basis for the analysis of the size deformation and deformation law of the turbine blades in each production process,and formulates corresponding control and preventive measures through the analysis of measurement data,so as to reduce the deformation of the blade in the casting production process,thereby reducing its quality repair and control cost in the production process,and improving production efficiency.
